떡이떡이Video: Volvo City Safety
이달 초 볼보가 공개한 City Safety 장치입니다. 흥미로운 영상인 것 같아 소개해 봅니다. 향후 유럽 및 일본에 출시되는 일부 럭셔리 시리즈에 이 광학 레이더 장치가 내장된다고 합니다. 2년 이내에 모든 볼보 시리즈로 확대한다고 하는군요.
2007년판 Volvo S80이 2007년 2월에 나오는데, 이 충돌 방치장치가 내장되는 첫 번째 모델입니다. 충돌이 예상되면 자동으로 브레이크가 작동됩니다. 전방 6m까지 인식합니다. 초당 50번씩 브레이크 동작 여부를 연산합니다.
볼보 테스트 자료에 따르면 두 대의 차간 거리가 시속 15km일 때 시속 30km까지 충돌을 막아준다는 설명입니다.
-----------------
Volvo has announced more innovative safety technology - a unique ‘City Safety' system that could help drivers avoid 50 per cent of all rear-end, low speed accidents that often happen in urban environments or slow moving traffic.
Statistics reveal that 75 per cent of all reported collisions occur at low speeds of up to 18.7 mph. The Volvo system, called ‘City Safety', is active up to 18.7 mph and keeps a watchful eye on traffic up to six metres in front of the car with the help of an optical radar system integrated into the upper part of the windscreen. If a car in front suddenly brakes or is stationary, the system will automatically pre-charge the brakes to help the driver avoid an accident by slowing down in time, or steering away from a potential collision. However, if a collision is imminent, the system will activate the car's brakes automatically.
“The system offers benefits to all involved. For the occupants of the car in front, the risk of whiplash injuries is avoided or reduced, plus it can help reduce or even eliminate the cost of repairs to both vehicles,” says Ingrid Skogsmo, director of the Volvo Cars Safety Centre.
The system runs a calculation 50 times per second to determine what braking speed is needed to avoid a collision based on the distance to the object in front and the car's own speed. If the calculated braking force exceeds a given level without the driver responding, the danger of a collision is considered imminent and ‘City Safety' helps avoid or reduce the consequences of a collision by automatically activating the car's brakes and reducing the throttle.
Certain LimitationsThe ‘City Safety' system works equally well day or night, but will have the same limitations as any other radar systems, so can be limited by fog, mist, snow or heavy rain. If the sensor on the windscreen is obscured by dirt or snow the driver is alerted via the car's information display.
“It is important to emphasise that the system does not absolve the driver from driving with adequate safety margins in order to avoid collisions. The automatic braking function is only activated when the system assesses that a collision is imminent. The system then steps in to limit the consequences of the imminent collision or, in some cases, totally avoid it,” explains Ingrid Skogsmo.
Preventive SafetyThe ‘City Safety' system should be available within two years. However, Volvo recently introduced Collision Warning and Brake Support active safety systems with the all-new Volvo S80, which also help to avoid and reduce damage and injuries from collisions. These systems alert the driver via audible and visual signals if the gap to the car in front is reducing so quickly that an impact is likely. It automatically pre-charges the braking system so that braking is as effective as possible in an emergency situation but doesn't offer full auto-braking.
